Description Cameron Meadors 2005-08-17 15:36:01 UTC 
If I try to play an ogg file with anything that uses gstreamer as the backend,
all I get is loud static.  This happens with the alsa, oss, and esd gst backends.
Comment 1 Takashi Iwai 2005-08-17 15:45:06 UTC 
How can I reproduce this bug in the simplest way?  Anyway, try beta2...

If this happens with OSS and if the device isn't blocked, I suspect a problem of
gstreamer plugin rather the sound backend.  You can check fuser /dev/snd/pcm*
and /dev/dsp* whether any devices are occupied.
Comment 2 Cameron Meadors 2005-08-18 14:23:47 UTC 
it works in Beta 2.
Comment 3 Cameron Meadors 2005-08-26 13:58:15 UTC 
This is back in beta 3.  All static again for ogg/vorbis files.  This time it
only does it with the alsa backend.  oss and esd backends sound fine.  Other
formats sound fine with all backends.
Comment 4 Cameron Meadors 2005-08-26 14:27:48 UTC 
Actully, it seesm to only be a problem when using gst-launch.  Rhythmbox and
banshee both play the files fine.
Comment 5 Takashi Iwai 2005-08-26 14:39:56 UTC 
Interesting, I got a bugreport with banshee on beta3, which symptom sounds
similar with this.  See #113316.

BTW, run alsamixer on a terminal and then run gstreamer to see whether it
changes the volumes.  It's important to know whether it changes the mixer or it
produces silent sound data.

Added maintainer to Cc.
Comment 7 Cameron Meadors 2005-08-26 15:16:48 UTC 
Let me restate the problem for clarity.  If I run the command

  gst-launch filesrc location=somefile.ogg ! spider ! alsasink

I get static.  If I run this command

   gst-launch filesrc location=somefile.ogg ! spider ! osssink

I get a clear rendering of the music encoded in the ogg file.  This is also true
if I use Rhythmbox or Banshee to play the same ogg, if the gstreamer backend is
set to alsasink with gstreamer-properties.

The volume level does not matter.  Running gst-launch does not change the volume.

Since most people will not use gst-launch it doesn't seem to be that important
if the real apps work fine.  Although this should be fixed.
Comment 8 Cameron Meadors 2005-08-26 15:36:25 UTC 
I have discovered that the static is only is the left channel.  The right
channel is noisy and quite, but you can here contents of the ogg file.
Comment 9 Takashi Iwai 2005-09-23 09:23:03 UTC 
Any chance to try rc4?  I fixed a bug in alsa-lib and this might improve this
case, too...
Comment 10 Mark Gordon 2005-09-23 15:52:09 UTC 
I'd been able to reproduce the problem in the past, but it's working for me in
RC4.  Closing as FIXED.
